Patent EP-0178757-A3 (EP)
IPC: G05D25/02
Filed: 1985-08-07
Abstract: Apparatus for regulating the voltage output of a solar 
cell array by selectively actuating individual cells that have 
been constructed to include a light control valve capable of 
being rendered opaque or transparent under electrical 
control. By automatically controlling selected cells in the 
array in this manner, the output characteristics of the array 
can be regulated to compensate for variations caused by 
temperature or other changes.
Patent EP-0187549-A3 (EP)
IPC: C25B9/23
Filed: 1985-12-31
Abstract: A system and method for dewatering or separating 
particles from a liquid or a colloidal suspension comprises 
the use of an electrofilter with separated, submerged 
electrodes (40, 50) the electrode (40) used for collecting the 
solid particles comprises an assembly (42) of an ion-selective 
membrane shell (48), coated with or having bonded on its 
interior, a conductive metal composite catalyst layer 56, and 
a conductive structural material core 58 such as graphite 
within the shell. The electrode assembly does not require the 
use of an electrolytic solution within the shell, but may be 
operated with one. A direct current is applied to the 
electrofilter so that the particles in the suspension will 
migrate towards the electrode assembly (42) and form a 
caked deposit or slurry layer on the outside of the mem­
brane. In one embodiment, the electrode assembly can be 
removed from the electrofilter cell so that the dewatered or 
separated solids may be removed from the outside surfaces 
of the membrane.

IPC: A47L7/00
Filed: 1986-01-10
Abstract: A liquid aspirator which may be connected to a conven­
tional vacuum cleaner has two separate body parts. The rear 
body part is provided with an extended tube into which can 
be inserted a hose from a conventional vacuum cleaner. Also 
the rear body part holds a cartridge which contains a filter

connected to the front nozzle of the front body part. The tube 
extends along the top of the front body part and protrudes 
through the filter cartridge to the back of the rear body part. 
The liquid aspirated by suction of the vacuum cleaner is 
discharged to the rear of the assembled unit. The filter 
cartridge slows down air and water speed and distributes 
liquid to the front liquid reservoir.

Abstract: Tissue expander system including a tissue expander, an 
injection port, and a tube connecting the tissue expander to 
the injection port. The tissue expander is of a one piece 
molded body of a pancake to waffle like configuration. 
Within the one piece molded body is a member of non-stick 
material of a slightly smaller geometrical shape simular to 
that of the one piece molded body. A self-sealing valve 
member closes off the tube in the tissue expander after 
injection of a solution for expanding the tissue expander. A 
dacron mesh can be embedded in members of the one piece 
body providing for directional expansion of the tissue 
expander. In an alternative embodiment, dacron mesh can 
be provided in both the upper and lower members of the one 
piece body. An accordion configured perimeter also provides 
for upward directional expansion. The tissue expanders can 
assume any geometrical configuration, whether it be square, 
rectangular, circular, oval or kidney shaped. The tissue 
expander can also be a small enough size for hands and toes, 
a miniature size for use on the face, or a large size for use on 
the chest or other body area. A self-sealing injection port can 
be domed or cylindrical, and includes a stainless steel 
bottom, as well as a dacron mesh impregnated silicon top. 
The stainless steel bottom provides for limiting injection 
needle penetration and for injection port location during 
X-ray procedure.

Title: Communications connector
IPC: H01R12/70
Filed: 1987-01-22
Abstract: A performed electrical insulation displacement connec­
tor is disclosed which enables electrical continuity between 
telecommunications equipment whose multiple electrical 
leads are commonly on a 0.085 inch pitch (center line dis­
tance between conductors) and other types of electronic 
equipment whose multiple electrical leads are commonly 
on a 0.050 inch pitch. A pair of 25 conductor arrays are pre­
formed for rapid and facile assembly assuming upper and 
lower rows in an insulative housing. Contacts are mounted 
at the forward end of the housing so they assume the 0.085 
inch pitch and can be engaged by a conventional multiple 
contact plug and bifurcated tails are mounted at the aft end 
of the housing to engagingly receive successive leads of a 
conventional ribbon cable which has a 0.050 inch pitch. If 
desired, the housing can accomodate a plural contact ca­
pacitor filter array adapted to be electrically engaged by the 
conductor arrays. One or more brackets composed of elec­
trically conductive spring material serve to ground the ca­
pacitor filter array. In one embodiment, such a bracket also 
serves to hold the array fixed in position within the housing. 
A cover removably mounted on the housing serves to en­
gage the ribbon cable at the aft end of the housing and to 
hold it firmly in position against the bifurcated tails.

IPC: G03C5/38
Filed: 1988-06-27
Abstract: The invention provides for the treatment of fixer 
medium in photographic processing. One the one hand, 
the fixer medium is extracted from the fixer station to 
a first treatment tank in which it is subjected to 
light electrolysis for regeneration of the fixer medium 
so that it can be re-circulated to the fixer station. 
When the fixer medium has reached a predetermined 
saturation condition of silver content, it is 
discharged from the first treatment station to a second 
treatment station where it is subjected to electrolysis 
for the removal of the silver. On the other hand, the 
fixer medium is constantly circulated from the fixer 
station to an electrolytic cell in which silver is 
extracted under an automatic control device which 
ensures that the electrolysing current is increased or 
decreased dependent upon the silver content of the 
fixer medium to ensure that the silver content keeps to 
a sensibly constant predetermined value.
